Resumo: This study aimed to evaluate energetic feedstuffs regarding chemical composition, in situ ruminal degradability of dry matter (DMD), ruminal kinetics and ruminal disappearance rate of dry matter. Seven feedstuffs (treatments) were evaluated: ground corn, ground oat, ground barley, wheat bran, soybean hull, malt root and corn germ, in a completely randomized design of four repetitions each. Two bovines ruminally cannulated were used for incubation, wherein each treatment was subjected to seven periods of exposure to the rumen (0, 3, 6, 9, 12, 18 and 24 hours). Among the evaluated feedstuffs, soybean hull had the highest neutral detergent fiber (NDF) content (68.91%) and the lowest DMD at 24 h (64.91%). Ground barley and ground corn contained the lowest content of soluble fraction (SF) (26.34 and 28.7%, respectively), among which ground barley had the highest DMD at 24 h (90.48%) and therefore showed the highest rumen disappearance rate (2.50%.h-1) by combining both parameters, while the ground oat presented the highest SF (47.75%) and the lowest rumen disappearance rate (1.09%.h-1).Key words: chemical composition; grains and industrial derivatives; ruminal disappearance rate

Foram avaliados sete alimentos (tratamentos): grão de milho moído, grão de aveia moído, grão de cevada moído, farelo de trigo, casca de soja, radícula de malte e gérmen de milho, num delineamento inteiramente casualizado com quatro repetições cada. Para a incubação dos materiais foram utilizados dois bovinos com cânula ruminal, e cada tratamento foi submetido a sete períodos de exposição ao rúmen (0, 3, 6, 9, 12, 18 e 24 horas). Dentre os alimentos avaliados, a casca de soja teve o maior teor de fibra em detergente neutro (68,91%) e apresentou a menor DMS em 24 h (64,91%). O grão de cevada moído e o grão de milho moído tiveram os menores níveis de fração solúvel (FS) (26,34% e 28,7%, respectivamente), porém o grão de cevada moído apresentou a maior DMS em 24 h (90,48%), que por conciliar estes parâmetros teve a maior taxa de desaparecimento ruminal (2,50%.h-1), enquanto o grão de aveia moído teve a maior FS (47,75%) e a menor taxa de desaparecimento ruminal (1,09%.h-1).Palavras-chave: composição química; grãos e derivados industriais; taxa de desaparecimento ruminalUniversidade Federal de Goiás2021-11-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistas.ufg.br/vet/article/view/68993Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 22 (2021): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 22 (2021): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/68993/37504https://revistas.ufg.br/vet/article/view/68993/37941https://revistas.ufg.br/vet/article/view/68993/37505https://revistas.ufg.br/vet/article/view/68993/37942Copyright (c) 2021 Ciência Animal Brasileirahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNeumann, MikaelSantos, Leslei CarolineAskel, Eloize JaquelineVenancio, Bruno JoséPontarolo, Giovanna Bobato Cristo, Fernando BragaPlodoviski, Daniel CorrêaSilva, Emylli Pereira e2023-03-23T18:53:00Zoai:ojs.revistas.ufg.br:article/68993Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:28.144091Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
